[0002] Taking a washing machine as an example, the vibration noise problem of the washing machine has always been a problem that manufacturers and users pay more attention to, and whether the feet are leveled is crucial to the vibration of the whole machine. If the washing machine feet are not leveled, it is easy to cause a series of problems of the whole machine, for example, the vibration noise is large, and the washing machine is displaced, walks and the objects placed on the washing machine fall off due to the large vibration amplitude. At present, the washing machine needs to be leveled manually after installation. Manual leveling is difficult, time-consuming and laborious, and it is easy to appear the phenomenon that the leveling is not good. SUMMARY

[0003] Therefore, the embodiments of the present application expect to provide a base device and a clothes processing apparatus capable of automatic leveling.

[0004] The embodiments of the present application provide a base device, comprising:

[0005] a base;

[0006] at least one first foot arranged at the bottom of the base;

[0007] a leveling mechanism arranged at the bottom of the base, each of the first feet and the leveling mechanism jointly bear the base, the leveling mechanism comprises two second feet and a crossbeam connecting the two second feet, in the leveling process, the crossbeam can be inclined relative to the horizontal plane to adjust the support height of each of the second feet.

[0008] In some embodiments, the base is provided with a containing cavity, the bottom side of the containing cavity is open; the leveling mechanism can be placed into the containing cavity from the open part of the containing cavity.

[0009] In some embodiments, the base device comprises a limiting piece, the limiting piece is detachably connected with the base and restricts the crossbeam in the containing cavity.

[0010] In some embodiments, the base is provided with a buckling groove on each of the opposite sides perpendicular to the length direction of the crossbeam, the limiting piece has at least two hooks, the hooks are buckled into the buckling grooves, and at least a part of the limiting piece is located below the crossbeam.

[0011] In some embodiments, the leveling mechanism bears the base through each of the second feet, and the crossbeam does not bear the weight of the base.

[0012] In some embodiments, the leveling mechanism forms at least two support points on the base, and the positions of the support points are synchronously changed during the leveling process.

[0013] In some embodiments, the crossbeam is rotationally connected to the base, and the crossbeam swings around the rotational connection to drive the second feet to move during the leveling process.

[0014] In some embodiments, the leveling mechanism forms only one support point on the base, and the support point is located at the rotational connection between the crossbeam and the base.

[0015] In some embodiments, the circumferential surface of the second foot is formed with a support protrusion; the base has a first protruding portion and a second protruding portion protruding from the side wall surface of the accommodating cavity, the first protruding portion and the second protruding portion are arranged along the length direction of the crossbeam, the first protruding portion is formed with a first downwardly inclined guide surface, the second protruding portion is formed with a second downwardly inclined guide surface, the normal line of the first guide surface and the normal line of the second guide surface intersect above the base; the support protrusion of one of the second feet is in sliding fit with the first guide surface, and the support protrusion of the other second foot is in sliding fit with the second guide surface.

[0016] In some embodiments, the second foot is provided with a support protrusion on each of the opposite sides in the direction perpendicular to the length direction of the crossbeam, and the accommodating cavity is provided with the first protruding portion and the second protruding portion on the side wall surface of each of the opposite sides in the direction perpendicular to the length direction of the crossbeam.

[0017] In some embodiments, the first protruding portion and the second protruding portion are integrally formed with at least the structure of the base around the accommodating cavity.

[0019] Taking the application of the base device to a clothing processing device as an example, when the clothing processing device is placed on a flat surface, the support heights of the two second bases are the same, and the forces acting on the two second bases are roughly even. When the clothing processing device is placed on an uneven surface, the base transmits a force to the leveling mechanism, causing one of the second bases to touch the ground first, while the other second base has not yet touched the ground. Under the action of the force transmitted by the base and the reaction force of the ground, the second base that touches the ground first forces the leveling mechanism to slide relative to the base as a whole, causing the crossbeam to gradually tilt. During the tilting process, the height of the connection point of the crossbeam with the second base changes, and the support height of the second base that touches the ground first gradually decreases. The crossbeam forces the second base that has not yet touched the ground to gradually move downward. In other words, the support height of the second base that has not yet touched the ground gradually increases until it touches the ground. At this point, both second bases touch the ground, and the forces acting on the two second bases are roughly even, thereby placing the clothing processing device in a leveled state and automatically adapting to the uneven surface.

[0020] The laundry processing device of the present invention utilizes a leveling mechanism to automatically level the laundry processing device, eliminating the need for manual leveling. After automatic leveling, even if the laundry processing device vibrates, the base and the second feet will not experience relative vertical movement, effectively reducing the vibration amplitude and vibration noise of the laundry processing device. Furthermore, after leveling, there is no need to manually tighten the second feet and the base, reducing the operational requirements for users or after-sales personnel.

[0037] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0038] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0039] The present application embodiment provides a base device, seeFigure 2 The base 2, at least one first foot arranged at the bottom of the base 2, and the leveling mechanism 1 arranged at the bottom of the base 2.

[0040] The leveling mechanism 1 and each first foot jointly bear the base 2, that is, the leveling mechanism 1 and each first foot need to bear the weight of the base 2 and the load acting on the base 2.

[0041] It should be noted that each first foot and the leveling mechanism 1 form at least three support points for the base 2, and each support point jointly defines a stable support plane to stably support the base 2. It should be noted that the support plane is approximately located in the horizontal plane.

[0042] For example, when the leveling mechanism 1 forms one support point for the base 2, the number of first feet is at least two, and each first foot forms one support point for the base 2. When the leveling mechanism 1 forms two support points for the base 2, the number of first feet can be one, two, or more.

[0043] The support point in the embodiment of the application refers to a force support point that can be simplified in the process of mechanical principle calculation, rather than a point in the mathematical sense.

[0044] Please refer to Figure 11 and Figure 13 The leveling mechanism 1 includes two second feet 12 and a cross beam 11 connecting the two second feet 12, that is, the two second feet 12 are connected through the cross beam 11. In the leveling process, the cross beam 11 can be inclined relative to the horizontal plane to adjust the support height of each second foot 12.

[0045] In the embodiment of the application, the cross beam 11 is a rigid member, that is, there is no relative movement between any parts of the cross beam 11.

[0046] It should be noted that the support height refers to the distance between the bottom end of the second foot 12 and the reference horizontal plane at the bottom edge of the base 2. For example, in the case that the base device is placed on a flat ground, please refer to Figure 6 The support height of the two second feet 12 is H1, wherein L1 indicates the ground, and L2 indicates the reference horizontal plane at the bottom edge of the base 2. Please refer to Figure 10 When the base device is placed on uneven ground, Figure 10 the support height of the second foot 12 on the right in Figure 10 is H3, and the support height of the second foot 12 on the left in is H2.

[0047] It should be noted that the above-mentioned reference horizontal plane is only illustrative, and the reference horizontal plane can also be selected as a horizontal plane passing through a certain determined position on the base 2.

[0048] It should be noted that the specific structure of the cross beam 11 is not limited to a straight rod, but can also be a curved beam or rod.

[0049] The inclination of the cross beam 11 relative to the horizontal plane means that the line connecting the two connection points of the second feet 12 is inclined relative to the horizontal plane. That is, whether the cross beam 11 is inclined, with the line connecting the two connection points as the reference. Among them, the connection point refers to a connection point that can be simplified in the process of mechanical principle calculation, rather than a point in the mathematical sense.

[0050] The application occasion of the base device is not limited, for example, it can be used in household appliances. The base device can be a part of the structure of the household appliance, that is, the base device constitutes an indispensable part of the household appliance. The base 2 can also be a separate accessory from the household appliance, for example, according to actual use needs, the household appliance can be directly placed on the base 2, or the household appliance can be taken off the base 2.

[0051] The embodiments of the present application take the household appliance as an example of a clothes processing device, wherein the base device is an indispensable part of the structure of the clothes processing device.

[0052] The embodiments of the present application provide a clothes processing device, which comprises a base device of any embodiment of the present application, a drum assembly and a cabinet assembly. The bottom side of the cabinet assembly is open and covers the base 2, and the drum assembly is arranged in the cabinet.

[0053] In this embodiment, the base 2 bears the weight of the drum assembly, the cabinet assembly and all loads of the clothes processing device. For the base 2, the drum assembly, the cabinet assembly and all loads of the clothes processing device collectively serve as the load borne by the base 2.

[0054] The specific type of the clothes processing device is not limited, which can be a washing machine, a clothes dryer, a washer-dryer, etc.

[0055] The working principle of the leveling mechanism 1 is as follows.

[0056] When the clothes processing device is placed on a flat ground, please refer to Figure 6 , the cross beam 11 is located in the horizontal plane, that is, the cross beam 11 is not inclined, the support heights of the two second feet 12 are the same, both are H1, and the forces of the two second feet 12 are substantially uniform.

[0057] When the clothes processing device is placed on uneven ground, please refer to Figure 10 , the base 2 transmits the force to the leveling mechanism 1, one of the second feet 12 touches the ground first, and the other second foot 12 has not yet touched the ground, for example, Figure 10The second feet 12 on the right side touch the ground first. Under the action of the force transmitted by the base 2 and the reaction force of the ground, the second foot 12 that touches the ground first forces the leveling mechanism 1 to slide relative to the base 2 as a whole, and the cross beam 11 gradually inclines. During the inclination of the cross beam 11, the height of the connection position of the cross beam 11 for connecting the second feet 12 changes, the support height of the second foot 12 that touches the ground first gradually decreases, and the cross beam 11 forces the second feet 12 that have not yet touched the ground to gradually move downward, that is, the support height of the second feet 12 that have not yet touched the ground gradually increases until the second feet 12 touch the ground. At this time, both of the second feet 12 touch the ground, and the leveled state is shown in FIG. 13. Figure 10 The forces on the two second feet 12 are basically the same, so that the clothes processing apparatus is in a leveled state and automatically adapts to the uneven ground.

[0058] The clothes processing apparatus of the embodiment of the present application realizes automatic leveling of the clothes processing apparatus through the leveling mechanism, and does not need human intervention for leveling.

[0059] In the related art, a spring is arranged on the foot, and the clothes processing apparatus is automatically leveled through the deformation of the spring. However, during the vibration of the clothes processing apparatus, the machine body and the foot have relative movement. On the one hand, the spring easily causes the machine body to resonate, and aggravates the vibration amplitude of the clothes processing apparatus. On the other hand, during the vibration, the machine body can move downward relative to the foot, and the vibration amplitude of the machine body is large.

[0060] The base device of the embodiment of the present application does not have relative movement between the base 2 and the second feet 12 after automatic leveling, and can effectively reduce the vibration amplitude and vibration noise of the clothes processing apparatus. In addition, after leveling, the second feet 12 and the base 2 do not need to be locked by a person, and the operation requirement of the user or the after-sales personnel is reduced.

[0061] It should be noted that the first feet can be fixed feet, or feet provided with telescopic springs, etc. In the embodiment in which the number of the first feet is multiple, the first feet can be independent of each other and do not interfere with each other. Alternatively, at least two first feet are linked to form the leveling mechanism 1 of the embodiment of the present application, that is, the base device is provided with at least two leveling mechanisms 1 of the embodiment of the present application.

[0062] The connection mode of the cross beam 11 and the second feet 12 is not limited. For example, in some embodiments, the cross beam 11 is hinged to the second feet 12. In this way, after the cross beam 11 is in an inclined state, the second feet 12 are still in a vertical support state.

[0063] In some other embodiments, the cross beam 11 is fixedly connected with the second foot 12, wherein the fixed connection refers to a connection mode in which the cross beam 11 and the second foot 12 are not allowed to move relative to each other, such as welding, clamping, riveting, bolt connection, etc.

[0064] For example, referring to Figure 2 , Figure 3 and Figure 4 , the base 2 is provided with a receiving cavity 2a extending along the length direction of the cross beam 11, and the bottom side of the receiving cavity 2a is open. Referring to Figure 6 and Figure 10 , the leveling mechanism 1 is disposed into the receiving cavity 2a from the open side of the receiving cavity 2a. That is, the cross beam 11 is located in the receiving cavity 2a.

[0065] During assembly, the cross beam 11 and the two second feet 12 can be assembled into a pre-assembled whole, and then the pre-assembled whole is disposed into the receiving cavity 2a from the open side of the receiving cavity 2a. That is, during assembly, the leveling mechanism 1 and the base 2 can be assembled at the same station without needing to turn over the base 2 multiple times.

[0066] On the one hand, the receiving cavity 2a provides installation space for the cross beam 11 and the second feet 12, and also provides a certain protection, and on the other hand, the cross beam 11 is prevented from being exposed on the appearance surface of the clothes treatment device, other objects are prevented from scratching the cross beam 11, and the cross beam 11 is prevented from affecting the appearance of the clothes treatment device.

[0067] In the embodiments in which the base 2 is provided with the receiving cavity 2a, the cross beam 11 is fixedly connected with the second feet 12, so that it is not necessary to provide a guide and limiting structure for the second feet 12 on the base 2. It should be noted that in the embodiments in which the second feet 12 are hingedly connected with the cross beam 11, the second feet 12 need to be guided and limited to prevent arbitrary deflection of the second feet 12.

[0068] For example, the receiving cavity 2a is closed except for the bottom side, that is, the structure around the receiving cavity 2a is a continuous structure, which on the one hand improves the structural strength of the base 2, and on the other hand facilitates the manufacturing of the base 2.

[0069] The material of the base 2 is not limited, and can be metal, plastic, etc.

[0070] For example, the base 2 is an integrally formed injection molding part, that is, the material of the base 2 is plastic, which is beneficial to reducing the cost of the base 2 and facilitating the manufacturing of the base 2 into a complex process shape.

[0071] The specific structural shape of the base 2 is not limited.

[0072] Exemplarily, the base 2 is substantially in a frame structure. Please refer to Figure 1 , Figure 2 and Figure 5 , the base 2 comprises a plurality of supporting arms 21, which are connected end to end to define a hollow region 2b. Each supporting arm 21 is a structural member. With this structure, the hollow region 2b is beneficial to reduce the material usage and the weight of the base 2.

[0073] Exemplarily, please refer to Figure 1 , the base 2 further comprises a first barrier wall 22 and a second barrier wall 23. The first barrier wall 22 is arranged on one side of one of the supporting arms 21 facing the hollow region 2b, and the second barrier wall 23 is arranged on the top of the space enclosed by the corresponding supporting arm 21 and the first barrier wall 22. The first barrier wall 22, the second barrier wall 23 and the corresponding supporting arm 21 together define the accommodating cavity 2a. In this embodiment, the first barrier wall 22 and the second barrier wall 23 do not affect the appearance of the base 2, do not change the appearance size of the base 2 along the circumference, and do not affect the height size of the base 2.

[0074] It should be noted that the second barrier wall 23 does not exceed the top surface of any one of the supporting arms 21, so as to avoid affecting the installation of the base 2 with the cabinet assembly and the barrel part.

[0075] It should be noted that after the leveling mechanism 1 is placed into the accommodating cavity 2a from the open side of the bottom of the accommodating cavity 2a, it is necessary to ensure that the leveling mechanism 1 is not easily dropped out of the accommodating cavity 2a during assembly, handling and the like.

[0076] Exemplarily, in some embodiments, the base 2 is formed with a spring piece. One end of the spring piece is fixed on the base 2, and the other end of the spring piece extends into the open side of the accommodating cavity 2a. During the process of placing the cross beam 11 into the accommodating cavity 2a, the cross beam 11 forces the spring piece to elastically deform. When the cross beam 11 passes the spring piece, the spring piece restores under the action of its own elastic force. The spring piece plays a role of limiting and stopping the cross beam 11, so as to prevent the cross beam 11 from being dropped out of the open side of the accommodating cavity 2a. It should be noted that when the base is placed on the ground, the spring piece will not bear the force of the cross beam 11, and the spring piece is in a state of not being stressed.

[0077] In other embodiments, please refer to Figure 2 , Figure 6 , and Figure 9 , the base device comprises a limiting piece 3, which is detachably connected with the base 2 and is used for restraining the cross beam 11 in the accommodating cavity 2a.

[0078] Specifically, during the assembling process, the leveling mechanism 1 is placed into the accommodating cavity 2a, and then the limiting piece 3 is connected with the base 2, so that the limiting piece 3 does not affect the assembling of the leveling mechanism 1, and in addition, when the leveling mechanism 1 needs to be disassembled, the limiting piece 3 is disassembled, and then the leveling mechanism 1 is taken out. In addition, since the limiting piece 3 does not affect the assembling of the cross beam 11, the limiting piece 3 can be designed into any shape as required, which improves the design flexibility of the limiting piece 3 and also improves the limiting reliability of the limiting piece 3 on the cross beam 11.

[0079] The specific structure of the limiting piece 3 is not limited as long as it can conveniently limit the cross beam 11.

[0080] For example, referring to Figure 3 and Figure 4 , the base 2 is provided with a buckling groove 2c on each of opposite sides perpendicular to the length direction of the cross beam 11, that is, the number of buckling grooves 2c is at least two. Referring to Figure 12 , the limiting piece 3 has at least two hooks 31, the hooks 31 are buckled into the buckling grooves 2c, and at least a part of the limiting piece 3 is located below the cross beam 11.

[0081] Specifically, the limiting piece 3 has a certain length, and the limiting piece 3 is provided with a hook 31 at each of opposite ends in the length direction, each hook 31 is buckled into a corresponding buckling groove 2c, and the limiting piece 3 passes from below the cross beam 11. In this embodiment, the assembling process of the limiting piece 3 is simple and convenient.

[0082] It should be noted that the specific position of the buckling groove 2c is not limited as long as the hook 31 of the limiting piece 3 can be buckled in.

[0083] For example, referring to Figure 3 and Figure 4 , the buckling groove 2c is formed in the bottom end face of the base 2. During the assembling process, it is convenient for the operator to press the hook 31 inwardly into the buckling groove 2c, and even one-handed operation can be realized, further simplifying the assembling process.

[0084] It should be noted that the hook 31 needs to have good structural strength, and during the assembling or carrying process, the cross beam 11 is abutted on the limiting piece 3 under the action of its own gravity, and the hook 31 is not easy to be pulled out of the buckling groove 2c.

[0085] The specific structure of the limiting piece 3 is not limited. For example, in some embodiments, referring to Figure 12 , the limiting piece 3 is an integrally formed plastic piece.

[0086] In some other embodiments, the limiting member 3 is in a split structure, and specifically, the limiting member 3 includes a flexible member and clamping hooks 31 connected to two ends of the flexible member. The flexible member can be a metal strip, a metal wire bundle, a woven belt, a rubber belt, etc., and the clamping hooks 31 can be made of plastic or metal.

[0087] In some embodiments, the base 2 can directly abut against the cross beam 11 of the leveling mechanism 1, that is, the force of the base 2 is first transmitted to the cross beam 11, and then transmitted to the second foot 12 through the cross beam 11. For example, the cross beam 11 is rotationally connected to the base, for example, hinged, and the adjustment of the support height of each second foot 12 is realized by swinging the cross beam 11 around the rotational connection.

[0088] In some other embodiments, the leveling mechanism 1 bears the base 2 through each second foot 12, and the cross beam 11 does not bear the weight of the base 2. That is, the cross beam 11 basically only bears tensile stress and basically does not bear shear stress, so that the requirements for the structural strength and bending stiffness of the cross beam 11 can be reduced.

[0089] For example, in some embodiments, the leveling mechanism 1 forms at least two support points for the base 2, for example, each second foot 12 forms one support point for the base 2, and two second feet 12 can form two support points for the base 2. During the leveling process, the positions of each support point change synchronously.

[0090] It should be noted that the synchronization in the embodiments of the present application refers to the synchronization in time, that is, the positions of each support point start to change at the same time and end to change at the same time.

[0091] For example, in some other embodiments, the cross beam 11 is rotationally connected to the base 2, and during the leveling process, the cross beam 11 swings around the rotational connection and drives each second foot 12 to move. In this embodiment, the leveling mechanism 1 forms only one support point for the base 2, and the support point is located at the rotational connection of the cross beam 11 and the base 2. For example, please refer to Figure 13 , the cross beam 11 is provided with an axle hole 11a, and a rotating shaft passes through the axle hole 11a and rotationally connects the cross beam 11 and the base 2. That is, during the swinging of the cross beam 11, the support heights of all second feet 12 can be adjusted synchronously.

[0092] Two embodiments of the present application will be introduced below in combination with the drawings.

[0093] Embodiment one

[0094] Please refer to Figures 1-11 , the leveling mechanism 1 bears the base 2 through each second foot 12, and the cross beam 11 does not bear the weight of the base 2.

[0095] The leveling mechanism 1 forms two supporting points to the base 2, wherein each second foot 12 forms one supporting point to the base 2. The crossbeam 11 is constrained in the accommodating cavity 2a by the limiting member 3.

[0096] Exemplarily, please refer to Figure 11 , the circumferential surface of the second foot 12 is formed with a supporting protrusion 12a, and the base 2 abuts against the supporting protrusion 12a.

[0097] Please refer to Figure 3 and Figure 4 , the base 2 has a first protruding portion 241 and a second protruding portion 242 protruding from the side wall surface 2a' of the accommodating cavity 2a, and the first protruding portion 241 and the second protruding portion 242 are arranged along the length direction of the crossbeam 11. The base 2 abuts against the supporting protrusion 12a of one of the second feet 12 through the first protruding portion 241, and abuts against the supporting protrusion 12a of the other second foot 12 through the second protruding portion 242.

[0098] Please refer to Figure 3 , Figure 4 , Figure 9 and Figure 10 , the first protruding portion 241 is formed with a first downwardly inclined guide surface 241a, and the second protruding portion 242 is formed with a second downwardly inclined guide surface 242a, and the normal line of the first guide surface 241a and the normal line of the second guide surface 242a intersect above the base 2. That is, the first guide surface 241a and the second guide surface 242a are arranged in a roughly back-to-back manner.

[0099] Please refer to Figure 6 and Figure 10 , the supporting protrusion 12a of one of the second feet 12 is in sliding fit with the first guide surface 241a, and the supporting protrusion 12a of the other second foot 12 is in sliding fit with the second guide surface 242a.

[0100] It should be noted that neither the first protruding portion 241 nor the second protruding portion 242 interferes with the crossbeam 11.

[0101] It should be noted that when the supporting protrusion 12a of one of the second feet 12 slides obliquely upward along the first guide surface 241a, the crossbeam 11 and the other second foot 12 move synchronously, so that the supporting protrusion 12a of the other second foot 12 slides obliquely downward along the second guide surface 242a. When the supporting protrusion 12a of one of the second feet 12 slides obliquely downward along the first guide surface 241a, the crossbeam 11 and the other second foot 12 move synchronously, so that the supporting protrusion 12a of the other second foot 12 slides obliquely upward along the second guide surface 242a.

[0102] It should be noted that the first guide surface 241a can be a flat, continuous surface, or an abstract surface defined by a plurality of protrusions. The second guide surface 242a can be a flat, continuous surface, or an abstract surface defined by a plurality of protrusions.

[0103] Exemplarily, referring to Figure 11 , the second foot 12 is provided with a support protrusion 12a on each of the opposite sides perpendicular to the length direction of the cross beam 11. Referring to Figure 3 and Figure 4 , the side wall surface 2a' of the accommodating cavity 2a on each of the opposite sides perpendicular to the length direction of the cross beam 11 is provided with a first protruding part 241 and a second protruding part 242, and the cross beam 11 is arranged between the two first protruding parts 241 and between the two second protruding parts 242.

[0104] In this embodiment, the base 2 acts on the two support protrusions 12a of one of the second feet 12 through the two first protruding parts 241, and the base 2 acts on the two support protrusions 12a of the other second foot 12 through the two second protruding parts 242, so that the stress condition of the leveling mechanism 1 is improved, and the reliability of the leveling mechanism 1 is improved.

[0105] It should be noted that the first protruding part 241 can be an independent component and assembled to the base 2. The second protruding part 242 can be an independent component and assembled to the base 2.

[0106] Exemplarily, the first protruding part 241 and the second protruding part 242 are integrally formed with at least the structure of the base 2 around the accommodating cavity 2a. In this way, the assembly process can be reduced, and the structural reliability of the connection between the first protruding part 241 and the base 2 can be improved, and the structural reliability of the connection between the second protruding part 242 and the base 2 can be improved.

[0107] The specific shape of the first protruding part 241 is not limited, for example, it can be block-shaped or rib-shaped. The specific shape of the second protruding part 242 is not limited, for example, it can be block-shaped or rib-shaped.

[0108] The specific shape of the support protrusion 12a is not limited. Exemplarily, the support protrusion 12a can be cylindrical, and the two support protrusions 12a are coaxially arranged.

[0109] The automatic leveling principle of the leveling mechanism 1 of the embodiment of the present application is as follows.

[0110] When the base device is placed on a flat ground, the cross beam 11 is in a horizontal plane, referring to Figure 6 , the support heights of the two second feet 12 are the same, both being H1.

[0111] When the base device is placed on uneven ground, referring toFigure 10 The weight of the base 2 and its load is transmitted to the first second foot 12 that touches the ground, Figure 10 The second foot 12 on the right side touches the ground first, and during the leveling process, Figure 10 The second foot 12 on the left side has not yet touched the ground, and at this time, under the action of the force transmitted by the base 2 and the reaction force of the ground, Figure 10 The second foot 12 on the right side slides along the second guide surface 142a to the right and up, and forces the cross beam 10 to rotate around the support protrusion 12a of the second foot 12 on the right side as the center of rotation, and the cross beam 11 gradually tilts in the counterclockwise direction in the figure, Figure 10 During the tilting of the cross beam 11, the cross beam 11 forces the second foot 12 that has not yet touched the ground to gradually move downward until the second foot 12 touches the ground, at which time both second feet 12 touch the ground and the forces on both second feet 12 are substantially the same, thereby allowing the clothes processing device to be in a leveled state and to automatically adapt to uneven ground.

[0112] Embodiment Two

[0113] Please refer to Figure 12 The cross beam 11 is rotationally connected to the base 2, for example, hinged. The leveling mechanism 1 forms only one support point for the base 2, which is located at the rotational connection between the cross beam 11 and the base 2. During the leveling process, the cross beam 11 swings around the rotational connection and moves the second feet 12.

[0114] In this embodiment, since the cross beam 11 is rotationally connected to the base 2, the rotational connection has already served as a limiting part for the cross beam 11, which can prevent the cross beam 11 from disengaging from the base 2, and therefore, in this embodiment, the limiting part 3 described above is not needed.

[0115] When the base device is placed on uneven ground, the weight of the base 2 and its load is transmitted to the first second foot 12 that touches the ground through the cross beam 11, and under the combined action of the force of the base 2 and the first second foot 12 that touches the ground, the cross beam 11 swings adaptively around the rotational connection as the center of rotation, forcing the other second foot 12 that has not yet touched the ground to gradually move downward until it touches the ground.
